Philodendron 'Xanadu', Thaumatophyllum xanadu
Philodendron xanadu, a distinctive variety within the diverse Philodendron genus, stands out for its unique foliage and compact growth habit. Unlike its towering relatives, the Xanadu presents a more manageable size for indoor cultivation, making it a popular choice among houseplant enthusiasts.
Philodendron xanadu features deeply lobed, glossy green leaves that radiate outward from a central stem, creating a dense, shrub-like appearance. Each leaf, with its intricate pattern and slightly ruffled edges, can grow up to 16 inches long (40 cm), contributing to the plant’s lush, vibrant look. The Xanadu’s compact, spreading habit makes it an ideal choice for those seeking the tropical allure of philodendrons without the vertical challenge.
Native: Originally believed to hail from Brazil, Philodendron xanadu is actually a cultivated variety, its exact origins somewhat of a mystery. It thrives in warm, humid environments, mirroring the tropical rainforests of South America, where philodendrons predominantly grow. It belongs to the arum family (Araceae), along with Zantedeschia (Calla Lily), Caladium (Angel Wing), Monstera (Swiss Cheese Plant), or Colocasia (Elephant Ear).
Plant Type and Habit: Philodendron xanadu is a perennial evergreen that grows in a dense, clump-forming habit, rather than climbing or trailing like many other members of its family. Its growth pattern is conducive to forming thick, bushy foliage, making it an excellent ground cover or standalone specimen in both indoor and outdoor settings.
Size: Typically, Philodendron xanadu reaches about 3-5 feet in height and spread (90-150 cm), making it a sizable yet manageable plant for indoor spaces. Its moderate growth rate allows enthusiasts to enjoy its development without constant repotting or pruning.
Flowers: Philodendron xanadu can produce flowers, particularly in outdoor environments in optimal conditions. Its inflorescences are similar to those of other philodendrons, featuring a spadix surrounded by a red spathe, though flowering is rare and not the plant’s main attraction when grown indoors.
Foliage: The foliage is undoubtedly its most striking feature. The dark green, glossy leaves with their unique lobes create a textural and visual depth, enhancing any space with their presence. The leaves are both sturdy and elegant, capable of purifying the air while adding a touch of nature’s artistry.
Hardiness: Philodendron xanadu is hardy in USDA zones 9b to 11, thriving in warm climates. It tolerates temperatures down to about 55°F (13°C) but prefers warmer conditions for optimal growth.
Uses: Philodendron xanadu is primarily cultivated for its ornamental value. It’s versatile enough to serve as a statement piece in living rooms, offices, or large open spaces, where its tropical essence can be fully appreciated. Additionally, its dense foliage makes it an effective air purifier, improving indoor air quality by removing toxins. In warmer climates, it’s also used in landscaping as an attractive, low-maintenance ground cover that provides year-round greenery.
Toxicity: Philodendrons are toxic to humans, cats, and dogs if ingested. They contain calcium oxalate crystals that can cause mouth and stomach irritation. Contact with the sap may cause skin irritation.
Deer and Rabbits: Its toxicity generally deters deer and rabbits.
Benefits: Beyond its decorative appeal, it also helps purify the air, removing toxins and improving indoor air quality.
Light: Philodendron xanadu prefers bright, indirect sunlight. Too much direct sun can scorch the leaves, while too little light may cause leggy growth. A spot near a window with sheer curtains is ideal.
Soil: Requires well-draining soil rich in organic matter. A mix of peat, perlite, and compost works well to ensure adequate drainage and nutrient retention.
Water: Water when the top inch of soil feels dry to the touch. Philodendron xanadu likes consistent moisture but is susceptible to root rot in soggy soil. Reduce watering in winter.
Temperature and Humidity: Thrives in temperatures between 65°F to 85°F (18°C to 29°C). Protect it from drafts and avoid exposure to temperatures below 55°F (13°C) to prevent stress. Enjoys high humidity, typical of its rainforest habitat. Mist the leaves regularly, use a humidifier, or place the plant on a pebble tray with water to increase humidity.
Fertilization: Feed with a balanced, water-soluble fertilizer every month during the growing season (spring and summer). Reduce feeding in fall and winter as growth slows.
Cleaning: Dust the leaves occasionally with a damp cloth to ensure the plant can photosynthesize efficiently. This also keeps the plant looking its best.
Pruning: Prune any yellow or damaged leaves to encourage new growth and maintain a bushy appearance. Trimming can also help manage its size and shape.
Repotting: Repot every 2-3 years or when the plant becomes root-bound. Choose a pot only slightly larger than the current one to avoid overwatering issues.
Propagating Philodendron plants is a straightforward and rewarding process, allowing you to expand your collection or share with friends and family. The most common method is stem cuttings, which can be rooted in water or soil. Here’s how to do it:
Choose a Healthy Stem: Look for a healthy stem with at least 2-3 leaves and a few nodes (the points on the stem where leaves attach and roots tend to grow).
Make the Cut: Using a clean, sharp knife or scissors, cut just below a node. The cutting should be about 4-6 inches long.
Prepare the Cutting: Remove any leaves that would be submerged when you place the stem in water to prevent rot.
Root in Water: Place the cutting in a glass or jar of water, ensuring the node is submerged. Leave the leaves out of the water. Place the jar in a warm, bright spot with indirect light.
Change the Water Regularly: Refresh the water every few days to keep it clean, which helps prevent bacterial growth.
Wait for Roots: Roots should start to emerge from the nodes in about 2-4 weeks. Wait until the roots are a few inches long before potting.
Potting: Once the roots are sufficiently developed, plant the cutting in a pot with well-draining soil. Care for it as you would a mature Philodendron.
Prepare Your Cutting: Follow the same steps as above to select and cut a healthy stem section.
Rooting Hormone (Optional): Dip the cut end of the stem in rooting hormone powder to encourage root growth. This step is optional but can enhance rooting success.
Plant the Cutting: Fill a pot with a well-draining potting mix. Make a hole in the center and insert the cut end of the stem, ensuring at least one node is buried beneath the soil surface.
Water and Cover: Water the soil lightly to settle it around the cutting. To create a humid microenvironment, you can cover the pot with a plastic bag or place it in a propagator. Ensure the leaves are not touching the plastic to prevent rot.
Care for Your Cutting: Place the pot in a warm, bright location with indirect light. Keep the soil consistently moist but not waterlogged.
Wait for Growth: In a few weeks, the cutting should start to root. You can gently tug on the plant after about 4 weeks; if there’s resistance, roots have formed.
Philodendrons can encounter pests, diseases, and other common problems, especially when grown indoors.
Spider Mites: These tiny pests can be identified by the fine webs they weave on the plant. They cause yellowing or speckled leaves. Increase humidity around the plant and wash it with a strong stream of water. For severe infestations, use insecticidal soap or neem oil.
Mealybugs: These white, cottony pests tend to cluster in leaf axils and under leaves, sucking sap and weakening the plant. Remove with alcohol-dipped cotton swabs or apply neem oil.
Aphids: Small, soft-bodied insects that can be green, black, brown, or pink, aphids typically feed in groups on the undersides of leaves. Combat them with a gentle spray of water, neem oil, or insecticidal soap to protect the plant’s health and appearance.
Scale insects: Hard or soft-bodied insects that attach themselves to the stems or leaves, causing yellowing and growth stunting. Scrape off with a fingernail or use a cotton swab dipped in rubbing alcohol. Insecticidal soap or neem oil may also be used.
Root rot: Overwatering is the primary cause, leading to brown, mushy roots and yellowing leaves. Reduce watering, improve drainage, and repot the plant into fresh, well-draining soil. Severely affected roots should be trimmed before repotting.
Leaf spot: Fungal or bacterial infections can cause dark or black spots on leaves, often with a yellow halo. Increase air circulation, avoid wetting leaves when watering, and remove affected leaves. Fungicides or bactericides may be necessary in severe cases.
Yellowing Leaves: Often a sign of overwatering or poor drainage. Ensure the soil is well-draining and allow the top inch to dry out between waterings.
Brown Leaf Tips or Edges: This can indicate low humidity or salt buildup from fertilizers. Increase humidity around the plant and flush the soil periodically to remove excess salts.
Drooping Leaves: Usually related to underwatering or extreme temperatures. Ensure consistent moisture and keep the plant away from drafts and extreme heat sources.
Leggy Growth: Insufficient light can cause sparse or leggy growth. Place your Xanadu in a location with bright, indirect sunlight to encourage fuller, healthier foliage.
Leaf Burn: Direct sunlight can scorch the leaves, leading to brown spots or patches. If exposed to direct sun, move your plant to a shadier spot.
